18 Given a target-files zipfile, produces an OTA package that installs
19 that build. An incremental OTA is produced if -i is given, otherwise
20 a full OTA is produced.
22 Usage: ota_from_target_files [flags] input_target_files output_ota_package
24 -b (--board_config) <file>
25 Specifies a BoardConfig.mk file containing image max sizes
26 against which the generated image files are checked.
28 -k (--package_key) <key>
29 Key to use to sign the package (default is
30 "build/target/product/security/testkey").
32 -i (--incremental_from) <file>
33 Generate an incremental OTA using the given target-files zip as
37 Generate an OTA package that will wipe the user data partition
41 Omit the timestamp prereq check normally included at the top of
42 the build scripts (used for developer OTA packages which
43 legitimately need to go back and forth).
45 -e (--extra_script) <file>
46 Insert the contents of file at the end of the update script.
48 -m (--script_mode) <mode>
49 Specify 'amend' or 'edify' scripts, or 'auto' to pick
50 automatically (this is the default).
